1820 Map: Viginia, Maryland, Washington, DC

S. Augustus Mitchell published this hand-colored map of Maryland, Virginia, and the District of Columbia in 1832, and included population data from the 1820 Census. During 1820 Census, 1,188 U.S. marshals and assistants counted 9,638,453 people in the nation's 23 states and its territories—a 33 percent increase in the population when compared to 1810. Along with population inquiries, marshals asked questions about each household's manufacturing pursuits as wells as the first census inquiries related to agriculture.

As shown by this map: Maryland's population in 1820 was 407, 350; Virginia had a population of 1,065,366; and the District of Columbia totaled 33,039. Today, Maryland and Virginia's populations are estimated to be 6,052,177 and 8,470,020, respectively. The population of the District of Columbia is 693,972. Learn more about the 1820 Census here.
